以下のコードがシリアライズ/アンシリアライズを維持しない限り、ページ全体で $_SESSION['objSession'] オブジェクトを永続化しない理由を理解しようとしています。セッションでオブジェクトを変更するために手動でシリアル化/非シリアル化することにうんざりしていて、人々はそれを行う必要はないと言い続けていますが、ここを含むWeb上でそれなしではセッションオブジェクトが持続しないという他の苦情を見ていますスタック... PHP 5.3 アパッチ 2.2 Windows 2008.
<?php require_once("/php/php_clsSession.php");?>
<?php session_start(); ?>
<?php
// Session Object Create/Log
$objSession = new clsSession;
if ( !(isset($_SESSION['objSession']) )) {
// This line will populate some properties in the obj
// like Session_ID and Create_dt
$objSession->CreateSession(session_id(),$_SERVER);
}
else {
// this code will only run if the session is already
// set
$objSession = unserialize($_SESSION['objSession']);
$objSession->UpdateSession(session_id(),$_SERVER);
}
// Update Session Object
$_SESSION['objSession'] = serialize($objSession);
unset($objSession);
?>
---- clsSession この行の下...コードにはdb機能を使用せずに同じ問題があり、とにかく一時的にコメントされたdb関数があるため、dbインクルードを無視できます....
